Definitions

  • the present invention relates to a device for twisting wires, with a twisted rod provided with a binding hook which is set into rotation upon pulling a handle part, for connecting rods, in particular steel reinforcement rods.
  • a plurality of devices for twisting wires are known as well as formed wires for carrying out the securement of steel reinforcement rods, this work mostly being performed by specialists under contract.
  • the steel rods used for the fabrication of reinforced concrete constructions usually lie one above the other orthogonally and have to be interconnected at their points of intersection.
  • a simple apparatus prevails which depends mainly on the specialized worker's skill and stamina.
  • prefabricated wire loops are used which have rings or eyelets at both ends.
  • two of these wire loops at a time are manually placed around the rods to be connected, and the four wire eyelets are seized by a twisting apparatus at the top.
  • This twisting apparatus comprises a rod with a hook, the rod being twisted and moving in a corresponding handle, so that the rod and, consequently, the hook, are set into rotation upon pulling the handle.
  • the hook is drawn out from the rings or eyelets. If the wire loops are tightened too strongly, it may occur that they break. Therefore, the people working under contract will be careful not to tighten the loops too strongly, which may result in a too loose connection.
  • the production of the wire loops with two rings or eyelets two of which have to be used in general, is relatively work-expensive and requires much material, which plays an important role considering the great quantities needed.
  • the object of the present invention to provide a device for twisting wires which always guarantees maximum securement and enables automatic disengagement of the binding hook from the loop, as well as a formed wire which is easy to produce, saves material and guarantees a safe and solid connection.
  • the device for twisting wires according to the invention is provided with a knurled rod having a binding hook which is set into rotation upon pulling a handle part, said binding hook being provided with means to release the same from the wire loop encircling it when the desired tightness of the connection is attained.
  • the device of the invention may be used particularly advantageously in connection with a device for connecting at least two rods according to PCT-A-WO87/01753, according to which the connection of two steel reinforcement rods is effected from above, without having to insert the wire underneath the steel rods by hand.
  • FIG. 1 shows, in a side view and partially sectioned, the inventively essential part of the twisting device
  • FIG. 2 shows a section along the line II--II of FIG. 1;
  • FIG. 3 shows a section along the line III--III of FIG. 1;
  • FIG. 4 shows a section along the line IV--IV of FIG. 1;
  • FIGS. 5 to 7 show three phases of the twisting procedure using the device according to FIG. 1;
  • FIG. 8 shows a formed wire to be used with the invention.
  • FIG. 9 shows a known wire loop.
  • the lower part of a device i.e. the binding hook and a mechanism for pivoting and releasing the same.
  • this releasing mechanism it is possible to twist the wires and to pull the binding hook from the loop with one single pulling movement.
  • the binding hook 4 is connected to the lower part of the housing 3 by an axle 5, as is apparent from FIG. 4 in particular.
  • the binding hook 4 is made of two parts, its two legs 4a and 4b being bent at the front, i.e. at the end 4c of the hook, and riveted together at the rear.
  • the legs 4a and 4b are provided with a recess 6 each, in which a stop slider 7 engages.
  • this stop slider is T-shaped and it is pressed into the recesses 6 by a pressure spring 8, the pressure spring S acting onto a guide washer 9 which rests on the short legs of the stop slider.
  • the pressure spring 8 with the leg of the stop slider 7 moving inside is guided in a hole 12 of a guiding piece 10, and its other end rests there.
  • the guiding piece 10 is secured in the housing 3, see FIG. 2.
  • the lower edges 11 of the stop slider, which engage in the recesses 6, are only little rounded off in order to provide for good locking.
  • the stop slider 7 not only acts onto the binding hook 4, but also onto a catch 13 which is arranged rotatively around a pin 14 and inside the two legs 4a and 4b of the binding hook. Now, if the catch 13 is moved upwards around the pin 14, i.e. in the direction of the knurled rod, the stop slider 7 is moved upwards against the pressure of the spring 8, in order to release the binding hook pivotable around the axle 5.
  • FIGS. 5 to 7 This releasing process is illustrated in FIGS. 5 to 7 by means of three distinct phases.
  • the two reinforcement rods 15 and 16 to be connected, as well as the wires to be twisted are represented in the phase in which the binding hook and the catch engage in the upper part of the formed wire.
  • This can be the wire loop 17 according to FIG. 8, wire clamps according to the above-mentioned PCT-A-WO87/01753, as will be explained hereinafter, or still other formed wires. Twisting of the wires, resp. rotation of the twisted rod is caused by a handle 20, which is only symbolically indicated here and which is provided with a through opening adapted to the cross-section of the twisted rod.
  • the catch 13 is pushed upwards to come into an approximately congruent position with the binding hook 4.
  • the notch part 21 of the catch 13 has lifted the stop slider 7 out from the recesses 6, so that upon further pulling, i.e. during the transition to the position according to FIG. 7, the binding hook and the catch are released, and, when pulling further, the hook and the catch slip from the upper part of the formed wire in FIG. 7.
  • the stop slider 7 now presses onto the rear end 22 of the binding hook and brings this and the catch 13 back into the initial position according to FIG. 5.
  • the present invention is not only suitable for this method and device for connecting at least two rods, but for any device for twisting wires.
  • the twisting device's lower end according to the invention is equally suitable.
  • the formed wire parts, resp. formed wires 18 with the eyelets 19 according to FIG. 9 are known, two of them being generally used at a time in order to obtain the desired strength.
  • the single wire loop 17 according to FIG. 8 was created which needs only one welding point 23 and of which only one loop has to be used at a time.
  • the twofold U-shaped bending and the single welding of the wire loop 17 necessitates less complicated tools and substantially less wire, whereby production costs can be reduced once more.
  • twisting devices are not limited to the building industry. In the packing industry or in viniculture, twisting devices are also used which may be equipped with the releasing mechanism described above, and the wire loop according to the invention ma be used there too.
